在复杂的断块及地层环境中,不稳定试井资料解释会遇到一定的困难。如在河流相沉积环境,因砂体平面连续性高度不确定导致不稳定压力试井会有几个符合试井资料的非单一结论。而通过借助地震属性分析资料来约束试井资料解释的多样性,可以更好地认识储藏边界及非均质性。本文将地质与试井相结合,运用地震属性分析及长时间压力恢复资料、岩心资料、测井及生产数据,减小了河流相储藏等复杂油藏描述的不确定性。
In complicated faulted blocks and formation environment, interpretation of unstable well test data will encounter some difficulties. For example, in a fluvial depositional environment, there are several non-single conclusions that are consistent with well testing data due to the high uncertainty of the continuity of the sand body plane. However, by using seismic attribute analysis data to constrain the diversity of interpretation of well test data, better understanding of reservoir boundaries and heterogeneities can be achieved. In this paper, the combination of geology and well testing, seismic attribute analysis and long-term pressure recovery data, core data, well logging and production data are used to reduce the uncertainty of complex reservoir description such as river phase storage.
